MSDS Sodium Chloride (NaCl) – Safety Data Sheet & GHS Hazards

Summary MSDS for Sodium Chloride (NaCl), CAS 7647-14-5: substance identity, GHS hazard classification, hazard and precautionary statements, and links to the manufacturer's official SDS.

Identity summary

Name	Sodium Chloride
Other names (IUPAC)	–
Molecular formula	NaCl
CAS number	7647-14-5
Molar mass	58.44 g/mol
PubChem CID	5234

Molar mass of NaCl and how to calculate it

The molar mass of NaCl is 58.44 g/mol, the sum of the relative atomic masses of all atoms in the formula: 22.990 + 35.450 = 58.44 g/mol.

Element	Atoms	Atomic mass	Contribution	Mass %
Na	1	22.990	22.99	39.34%
Cl	1	35.450	35.45	60.66%

So 1 mol of NaCl weighs 58.44 g, and 1 L of a 0.1 M solution needs 5.844 g of pure NaCl. For liquid or concentrated reagents, work from assay and density with the dilution formula. Calculate other compounds with the molar mass calculator.

Hazard identification (GHS)

This substance does not meet the GHS hazard criteria according to TCI official data. Still follow good laboratory practice: wear a lab coat and safety glasses and keep it in a closed, labelled container.

The GHS classification above matches TCI (Tokyo Chemical Industry) official data for product S0572 Sodium Chloride. Substance identity from PubChem CID 5234.

What is an MSDS/SDS?

An MSDS (Material Safety Data Sheet), now called an SDS (Safety Data Sheet), is a 16-section document describing the hazards, handling, storage, first aid, and disposal of a chemical. Read the full MSDS guide and other MSDS pages.
