Import Auramine O 2465-27-2 Dyes — Buy in wholesale FOB from Supplier in Hong Kong

Mit-IVY Chemical Industry Co., Ltd. supplies Auramine O under the designation name Auramine O 2465-27-2 Dyes, referencing the CAS number 2465-27-2 that identifies this material as Basic Yellow 2, a cationic diarylmethane dye. The company positions the product for direct dyeing and printing of textiles, colouring of leather, paper, and paint, and fluorescent staining of acid-resistant bacteria including Mycobacterium tuberculosis. This listing originates from a Hong Kong-registered entity with a correspondence address in Xuzhou, Jiangsu province, suggesting cross-border operational structure that buyers should clarify.

The dye's cationic nature enables strong affinity for acrylic fibres and mordanted cotton, while its fluorescence yield under UV excitation makes it suitable for both industrial coloration and microbiological diagnostic applications. Standard commercial grades typically exhibit maximum absorption near 370-380 nm in aqueous solution, with fluorescence emission around 440-450 nm, though these optical parameters are not lot-certified in the source data. Industrial users should note that Basic Yellow 2 is generally applied from acidic baths (pH 4-5) for acrylics, and compatibility with specific fibre types, acetate included, requires confirmation of substrate suitability and fastness performance.

Typical buyers span textile wet processors, leather finishers, paper colouration houses, paint manufacturers, and clinical diagnostics distributors. The listing mentions acetate fibre, mordant cotton, leather, paper, linen, and viscose as confirmed substrates, alongside ink colour lake preparation. Absent from the profile are specifics on dye strength, physical form (powder versus liquid), packaging configuration, MOQ, and lead time. All commercial and technical terms require direct confirmation with Mit-IVY Chemical Industry Co., Ltd.

Mit-IVY Chemical Industry Co., Ltd. is registered in Hong Kong with a listed address at 2-140, Shimao Plaza, Yunlong District, Xuzhou, Jiangsu 221000, indicating operational presence spanning Hong Kong and mainland China. The supplier holds a 'harbor' trust tier. Response rate and average response hours are both recorded at zero, so no responsiveness pattern is established through this channel.

The company profile does not state year of establishment, manufacturing facility ownership, workforce size, annual turnover, specific quality certifications, export licence numbers, or named clientele. What is confirmed is the dual-address structure and the product focus on cationic dyes with both industrial and diagnostic end-uses. Buyers should independently verify whether Mit-IVY operates as a manufacturer, trading company, or hybrid entity, and whether the Xuzhou address represents production, warehousing, or administrative functions only.
