Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 138308-78-8 2-ethyl-6-hydroxybenzaldehyde AS06356 BENZALDEHYDE, 2-ETHYL-6-HYDROXY-.

138308-78-8 2-ethyl-6-hydroxybenzaldehyde AS06356 BENZALDEHYDE, 2-ETHYL-6-HYDROXY- (CAS 138308-78-8), molecular formula C9H10O2 and molecular weight 150.17 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system, 138308-78-8 2-ethyl-6-hydroxybenzaldehyde AS06356 BENZALDEHYDE, 2-ETHYL-6-HYDROXY- is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 150.17 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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), 138308-78-8 2-ethyl-6-hydroxybenzaldehyde AS06356 BENZALDEHYDE, 2-ETHYL-6-HYDROXY- 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.
