Formaldehyde Standard Solution 5 ppm is a precisely calibrated aqueous solution containing formaldehyde (CAS 50-00-0, CH₂O) at a concentration of 5 parts per million, primarily used for analytical calibration in environmental testing, industrial hygiene monitoring, and regulatory compliance. This solution is supplied as a ready-to-use liquid reference standard for solution-phase methods, such as photometric and derivatization assays (for example acetylacetone/Nash or DNPH-based methods), HPLC, and water analysis. Key specifications include a nominal concentration of 5 ppm, stability for 12 months when stored unopened at ambient temperature, and a signal word of "Danger" due to formaldehyde’s hazardous nature. Molekula supplies Formaldehyde Standard Solution 5 ppm from research to bulk quantities with full documentation and ISO 9001:2015 traceability.
