MSDS Salicylic Acid (C7H6O3) – Safety Data Sheet & GHS Hazards

Summary MSDS for Salicylic Acid (C7H6O3), CAS 69-72-7: substance identity, GHS hazard classification, hazard and precautionary statements, and links to the manufacturer's official SDS.

Identity summary

Name	Salicylic Acid
Other names (IUPAC)	2-hydroxybenzoic acid
Molecular formula	C7H6O3
CAS number	69-72-7
Molar mass	138.12 g/mol
PubChem CID	338

Molar mass of C7H6O3 and how to calculate it

The molar mass of C7H6O3 is 138.12 g/mol, the sum of the relative atomic masses of all atoms in the formula: 7 × 12.011 + 6 × 1.008 + 3 × 15.999 = 138.12 g/mol.

Element	Atoms	Atomic mass	Contribution	Mass %
C	7	12.011	84.08	60.87%
H	6	1.008	6.05	4.38%
O	3	15.999	48.00	34.75%

So 1 mol of C7H6O3 weighs 138.12 g, and 1 L of a 0.1 M solution needs 13.812 g of pure C7H6O3. For liquid or concentrated reagents, work from assay and density with the dilution formula. Calculate other compounds with the molar mass calculator.
