    Applications

    Pharmaceutical Industry

    • API Synthesis: Used as the primary active ingredient in the production of rapid-acting vasodilators for the treatment of hypertensive emergencies and acute heart failure.

    Analytical Chemistry

    • Reagent Testing: Essential for Rothera’s test (detection of ketones in urine) and Simon’s test (detection of secondary amines like methamphetamine).
    • Sulfur Detection: Used to detect the presence of sulfide ions in aqueous solutions, turning purple in their presence.

    Industrial Research

    • NO Donor: Serves as a nitric oxide (NO) donor in physiological and pharmacological research studies.

    Quality Assurance (QA/QC)

    Our manufacturing process strictly adheres to Reagent Grade (ACS) and Pharmacopoeial (USP/BP/EP) standards.

    • Photosensitivity Control: Production and packaging are conducted in UV-shielded environments to prevent photodecomposition.
    • Impurity Analysis: We utilize IC (Ion Chromatography) to strictly limit chloride and sulfate impurities, ensuring the reliability of the reagent in sensitive analytical applications.
    • Traceability: Full batch documentation is maintained under ISO 9001:2015 protocols.

    Storage & Safety

    Storage Guidelines

    • Light Sensitivity: Store in amber bottles or opaque drums. Protect from light at all times; exposure causes decomposition to Prussian blue.
    • Environment: Keep in a cool, dry place. Keep the container tightly closed.
    • Moisture: The product is hygroscopic; avoid exposure to humid air.

    Safety & PPE Recommendations

    • Toxicity: This substance releases cyanide upon decomposition or metabolism. Handle with extreme care.
    • Respiratory Protection: Use a NIOSH-approved respirator equipped with dust/mist filters.
    • Skin & Eye Protection: Wear impervious protective clothing, gloves, and chemical safety goggles.
    • Emergency: In case of ingestion or extensive skin contact, seek immediate medical attention.

    FAQ - Technical & Supply Chain

    • Q:

      Does CAS 13755-38-9 correspond to the specific dihydrate form of the pentacyanonitrosylferrate complex?

      A: Yes. CAS 13755-38-9 identifies Sodium Nitroprusside Dihydrate, chemically defined as disodium pentacyanonitrosylferrate(II) dihydrate. It is structurally distinct from ferrocyanides and ferricyanides due to the presence of a nitrosyl (NO) ligand. This specific hydration state is the standard stable form used globally for both pharmaceutical synthesis and analytical reagent applications.
    • Q:

      Is Sodium Nitroprusside Dihydrate intended for pharmaceutical production rather than consumer applications?

      A: It is typically supplied as an industrial chemical intended for pharmaceutical synthesis or controlled reagent use, not as a direct consumer product.
