Chemical Structure

【禁售不询】Hydrochloric acid CAS 7647-01-0 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 【禁售不询】Hydrochloric acid.

【禁售不询】Hydrochloric acid (CAS 7647-01-0), molecular formula HCl and molecular weight 36.46 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 【禁售不询】Hydrochloric acid (HCl) contains chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 0, corresponding to approximately 0 ring(s) or double-bond equivalent(s). With a molecular weight of 36.46 g/mol, it falls into the low-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

As a certified reference material (CRM), 【禁售不询】Hydrochloric acid 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.
