Chemical Structure

Formaldehyde Sodium Bisulfite CAS 870-72-4 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Formaldehyde Sodium Bisulfite.

Formaldehyde Sodium Bisulfite (CAS 870-72-4), molecular formula CH3O4SNa and molecular weight 134.08 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a sulfone group, Formaldehyde Sodium Bisulfite is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 134.08 g/mol — guide the selection of appropriate sample preparation and analytical techniques.

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), Formaldehyde Sodium Bisulfite 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.
