Precise Chemical Identity and Purity Data
This compound, 1,4‑Butane Sultone (abbreviated 1,4‑BS), has the molecular formula C₄H₈O₃S and molecular weight approximately 136.17. It is offered with a minimum purity of ≥99.5 % for standard grades, and optionally higher purities (≥99.9 %) depending on requested specification. The acid value is limited to ≤0.20 mg KOH/g, and water content (Karl Fischer method) is no more than 0.10 %. Its appearance is a clear liquid that may be colorless to slightly yellowish. These data serve users requiring stringent material consistency, especially paint chemicals suppliers and coating chemicals developers who must control impurity levels and moisture to avoid side reactions or instability during processing.

Physical Properties and Handling Parameters
The compound has a melting point in the range of 12‑15 °C, which means below that temperature it may be solid or semi‑solid; at ambient temperatures above that it is typically a liquid. Its density at 25 °C is approximately 1.331 g/mL. Boiling behavior shows that under reduced pressure (25 mmHg) the boiling point exceeds 165 °C. Refractive index has been measured around n₍₂₀₎/D = 1.464. The compound is moisture sensitive and should be stored under conditions that prevent moisture uptake. Packaging is in 25 kg plastic drums. These properties and handling traits are important for operations by industrial coating supplier customers and all users in coating production chemicals supply chains to ensure stability and safe transport.

Regulatory and Application‑Relevant Behavior
1,4‑BS is a cyclic ester (a δ‑sultone), sometimes used as an alkylating agent. It reacts with nucleophilic functional groups such as hydroxyls or amines to introduce a sulfobutyl group. This functionality increases water solubility in derived compounds. The compound is characterized by warning and hazard classifications (GHS), indicating it is harmful by ingestion or skin/eye contact, and has weak carcinogenic activity in certain studies. Users in chemical coating and coating chemicals sectors must adhere to safety protocols. The compound’s reactivity and functional behavior make it applicable as an intermediate for surfactant or additive synthesis, or other speciality uses where a sulfobutyl group introduction is needed.

Product Advantages

High‑Grade Purity Reduces Contaminants
With ≥99.5% purity, low water content (≤0.10%), and controlled acid value (≤0.20 mg KOH/g), this 1,4‑BS reduces the risks of undesired side reactions, polymerization, or decomposition. For paint chemicals suppliers and coating production chemicals formulators, such high grade ensures better batch‑to‑batch consistency, less processing artefact, and fewer defects in final products.

Stable Physical Properties Support Reliable Processing
Melting point of 12‑15 °C, high boiling point under low pressure (>165 °C at 25 mmHg), density ~1.331 g/mL, and refractive index ~1.464 provide predictable behavior in mixing, heating, and storage. Its appearance (clear, faint yellow) gives visual cue for purity. These features assist industrial coating supplier operations in integrating it into existing process lines, dosing systems, or reaction vessels without unpredictable phase changes or handling surprises.

Packaging and Supply Chain Consistency
25 kg drums with standard export packaging ensure manageable units for storage, transport, and use. Lead times (15‑25 working days) are specified. Minimum order quantity is negotiable. Such supply stability is important to coating chemicals manufacturers and chemical coating customers who need reliable sourcing, consistency, and predictable lead times to support production scheduling.

Use Scenarios

Surfactant and Modifier Synthesis
When formulating surfactants or modifiers that require sulfobutyl functional groups, 1,4‑BS acts as the precursor to introduce such functionality. After reaction with nucleophiles, derived molecules gain improved solubility or charge distribution. This use is particularly relevant for coating production chemicals where modifiers help improve wetting, dispersion, or stabilizing behavior of coatings formulated by paint chemicals suppliers.

Fine Chemical Intermediate Paths
1,4‑BS is used in the synthesis of specialized ionic compounds, acids, catalysts, or conjugated polymers where introducing sulfonate groups is necessary. In cases where coatings or functional layers require ionic conductivity, or where protective coatings incorporate charged moieties, this intermediate plays a role. Users in industrial coating supplier space working on specialty or value‑added coatings may integrate this compound in multi‑stage chemical transformations.

Specialized Additive and Electrolyte Applications
Though not primarily used as a coating itself, 1,4‑BS’s application in lithium battery electrolyte additives (as noted) and related functional additive chemistry places it in adjacent sectors. Coating systems that interface with energy storage, electronics, or require conductive or protective layers may leverage materials produced using this intermediate. Chemical coating suppliers that cater to such cross‑domain requirements can use this compound to support additive production for multi‑functional coatings.
