As the May 1 International Labor Day holiday in 2026 approaches, for customers in the pharmaceutical, new materials, and fine chemical industries, pre-holiday stockpiling of raw materials directly affects the continuity of production after the holiday.

Shijiazhuang Feizi Chemical Technology Co., Ltd. (hereinafter referred to as “Feizi Chemical”)—in conjunction with its core inventory data—has released this pre-May Day stock-up guide, focusing on pharmaceutical intermediates and functional dye intermediates that have recently seen strong market demand. The guide is designed to help customers mitigate logistics risks and ensure uninterrupted production.

The holiday season continues without pause—now is the perfect time to stock up. The May Day holiday is not only a time for rest but also a crucial window for chemical enterprises to carry out maintenance and stock up on supplies. At Feizi Chemical, we deeply understand that the purity of raw materials and the timeliness of supply are the cornerstones of our company’s development. To this end, we’ve already conducted a comprehensive inventory and pre-shipment of our core product lines before the holiday, ensuring that our customers can resume production immediately after the holiday ends.

Core Product Line: The “Behind-the-Scenes Hero” of Pharmaceuticals and New Materials

Based on market demand and Feizi Chemical’s inventory levels, we strongly recommend the following core product categories. We advise relevant customers to place orders in advance according to their production schedules:

• Key intermediates for pharmaceuticals and pesticides (gold-level supply)

In our product library, several intermediates used in the synthesis of antihypertensive drugs, antibiotics, and pesticides are labeled as “gold” supply level—technologically mature and with ample inventory. Piperazine derivatives—such as 1-(2,3-dichlorophenyl)piperazine hydrochloride (CAS 119532-26-2) and 1-cyclohexylpiperazine (CAS 17766-28-8)—serve as crucial structural scaffolds for the synthesis of a variety of psychotropic drugs and antibacterial agents.

Uracil series: Includes 6-chloro-1,3-dimethyluracil (CAS 6972-27-6) and 1,3-dimethyl-6-aminouracil (CAS 6642-31-5), widely used in the research and development of antitumor and antiviral drugs. Chiral starting materials—such as D(-)-p-hydroxyphenylglycine (CAS 22818-40-2) and its potassium salt—are the key chiral sources for the semisynthesis of penicillins and cephalosporins. 2. Fine Chemicals and Dye Additives

For the textile printing and dyeing and industrial cleaning industries, Feizi Chemical offers high-purity sulfonic acid and color-developing agent products:

Surfactant raw materials: Pyridine p-toluenesulfonate (CAS 24057-28-1) and sodium isopropylbenzenesulfonate (CAS 28348-53-0), which exhibit excellent wetting and penetration properties. Functional dyes: the Acid Black 71 (CAS 127830-14-2) and Chromotropic acid disodium salt dihydrate (CAS 148-25-4) series, widely used for coloring and detecting leather, textiles, and paper.

Feizi Chemical: Safeguarding Supply Chain Security with the “Gold Standard”

During this May Day holiday, although Feizi Chemical will also enjoy a brief break, our commitment to service remains fully operational:

Express Channel Before the Holiday: By 6:00 p.m. on April 30, we will activate an expedited logistics channel to prioritize processing orders that require urgent shipment. Technical Support: For reactive compounds such as 3-cyano bromobenzene (CAS 22115-41-9) and 4-bromobenzaldehyde (CAS 1122-91-4), our technical team provides free storage and usage recommendations to ensure the safe and stable handling of these chemicals during the holiday period.
