Calcium Chloride

The CAS registry number for Calcium Chloride is 10043-52-4. Its chemical formula is CaCl2, with a molecular weight of 110.99 g/mol (anhydrous). Quote this number when requesting a quotation or checking documentation, as it identifies the substance unambiguously regardless of the trade name used.

Calcium Chloride is also referred to as Calcium Dichloride. These names describe the same substance, so a specification or enquiry written against any of them can be matched to this product.

Calcium Chloride is supplied as Technical grade. State the grade your process requires when requesting a quotation — where an alternative grade can be sourced, it is confirmed at quotation stage rather than assumed.

The purity/assay figure recorded for Calcium Chloride is Anhydrous: ≥93%, Dihydrate: 99-107%, Hexahydrate: 98-110%. Figures are typical values for the grade supplied; the certificate of analysis for your specific batch is the authoritative record and can be provided on request.

Calcium Chloride is described as white, odourless, hygroscopic powder or deliquescent crystals. Appearance is a useful first check on receipt of goods, though it does not replace the certificate of analysis for confirming that the material meets specification.

Common applications include de-icing and snow melting, road dust control, food processing for firmness and preservation, concrete acceleration in non-reinforced structures, oil and gas drilling fluids and water treatment for contaminant removal and remineralization. The suitability of the product for a particular process depends on the grade and specification required, which is worth confirming against your own process conditions.

Calcium Chloride is supplied to the Water Treatment, Food Processing & Beverage, Agriculture & Agrochemicals, Construction & Admixtures and Oil, Gas & Energy sectors. These are the industries this product is listed against in our catalogue; if your application falls outside them, we can advise on suitability before you order.

Calcium Chloride is supplied in 25 kg and 50 kg bags, 200 L drums. Where a different pack size or bulk delivery is required, it is confirmed at quotation stage against availability rather than listed here as standard.

Store in a tightly‑sealed, airtight container to protect from moisture due to its hygroscopic/deliquescent nature. This is general guidance only. The safety data sheet for the product supplied is the authoritative source for storage, handling and incompatibility requirements, and should be read before the material is received on site.

Calcium Chloride is recorded against the EC number 233-140-8 and the HS customs code 2827.20.00.00. Quote this on customs and export paperwork; it is confirmed again on the commercial invoice for your specific consignment.
