3-Chloro-2-hydroxy-6-methylbenzaldehyde CAS 153782-74-2 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 170.59 g/mol gives 3-Chloro-2-hydroxy-6-methylbenzaldehyde distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

3-Chloro-2-hydroxy-6-methylbenzaldehyde (CAS 153782-74-2), molecular formula C8H7ClO2 and molecular weight 170.59 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system, 3-Chloro-2-hydroxy-6-methylbenzaldehyde is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 170.59 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

As a certified reference material (CRM), 3-Chloro-2-hydroxy-6-methylbenzaldehyde meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
