Chromium(III) Hydroxide｜CAS 1308-14-1
Raw text: Bluish-green powder or green gelatinous precipitate; decomposes to chromium(III) oxide on heating; insoluble in water; soluble in dilute mineral acids when freshly prepared, becoming insoluble on aging; soluble in strong alkalis.
Basic Product Information
Product Name: Chromium(III) Hydroxide
CAS Number: 1308-14-1
Chemical Formula: CrH₅O₄
EINECS No.: 215-158-8
Synonyms: Chromic hydrate, Chromic(III) hydroxide
Appearance: Bluish-green powder or green gelatinous precipitate

Application Fields
Chromium(III) hydroxide serves as an essential intermediate raw material for chromium-series chemical production, widely adopted across multiple industrial sectors:
Chromium Salt Manufacturing: Primary precursor for producing other high-value chromium compounds, including chromium sulfate, chromium chloride and basic chromium salts.
Ceramic & Inorganic Pigment Industry: Used to formulate stable green oxide pigments for ceramic glazes, enamel coloring and high-temperature resistant coatings.
Tanning Industry: A classic raw material for chrome tanning agents in leather processing, helping improve leather softness, tensile strength and water resistance.
Catalyst Production: Applied as a chromium source for preparing heterogeneous catalysts used in hydrogenation, dehydrogenation and organic synthesis reactions.
Other Uses: Auxiliary additive for anti-corrosion paints, raw material for grinding and polishing agents, and feedstock for laboratory chemical research.

FAQ
Q1: What is your MOQ for chromium(III) hydroxide CAS 1308-14-1?
A: Our standard minimum order quantity is one full container load (FCL). We do not support LCL small parcel orders for this item currently.
Q2: Can you provide free samples for lab testing?
A: Small test samples are available. The buyer needs to bear the sample freight cost. After sample approval, formal FCL order can be arranged.
Q3: How should we store this product?
A: Store in cool, dry, well-ventilated warehouse. Seal packages tightly. Separate from acids, alkalis and oxidants. Avoid overheating, as heating will trigger decomposition into chromium(III) oxide.
Q4: Is this product hazardous for shipping?
A: Refer to MSDS for full hazard classification. Proper shipping name, hazard labels and supporting documents will be prepared to comply with international maritime transport rules.
Q5: What is your typical lead time after deposit?
A: Normally 7–15 working days upon receiving deposit, subject to production schedule and container availability.
Q6: Can you adjust product indexes for our special formula?
A: Yes. Please send your target specification sheet, we will evaluate and quote for custom grade production.
Safety Handling Reminder
Operators shall wear protective gloves, goggles and dust masks when handling the powder. Prevent dust inhalation and skin contact. In case of accidental contact, flush with plenty of clean water immediately. Do not discharge residual waste directly into the environment, follow local waste treatment regulations.
